There are a few different ways breeders are producing Goldendoodles.F1 = 50% Golden Retriever and 50% Poodle. This is Golden to Poodle cross; this is first generation, resulting in healthier offspring. Hair type can be smooth like a Golden, or wavy/shaggy or occasionally a wiry look like an Irish Wolfhound (but with a softer feel), they can shed or not shed, pups in the same litter can vary.F1-B= 25% Golden Retriever and 75% Poodle (F1 Goldendoodle and Poodle cross). This is Goldendoodle bred back to Poodle.F2 = F1 Goldendoodle and F1 Goldendoodle cross. With this combination you get the same percentage of Golden and Poodle mix as you would with an F1 Goldendoodle.F3 = F2 Goldendoodle and F2 Goldendoodle cross.Multi-generation = F3 or higher generation Goldendoodle and F3 or higher generation Goldendoodle cross.
